TO ALL WHOM IT MAY CONOEItN:

Be it known that I, HENRY F. KNAPP, 'ofv the city, county, and State ofNew York, have inventedn'J certainV new and useful Improvement onMachines for Making Collars, Cu's, Wristbands, and other iikc'articlesfrom papervor paper cloth, of which the following is a full, clear, andexact description, reference being had to the accompanying drawing,forming part of this specification, and in which l Figure 1 represents aside elevation of a machine adapted to the making of collars from paperor paper cloth, with my improvement applied to it.

Figure 2 is a vertical section of the saaie; taken transversely to theformer ligure.

Figure 3, a horizontal section through the line in tig. 1; and v Figure4 an inverted plan or under view of the upper or moving cutters in theirconnection withthe platen.

Like letters refcr tolike parts throughout the several igures.

This, my present invention, embraces many or most features in commonwith the machine described in Letters Patent of the United States, (No.59,4:10,)`issued` to me on the sixth vday of November, 1866, in whichwere combined, -in connection with cuttingblocks, a longitudinal knifeand cross-cntters, operating, in their joint descent, to intersect eachother in their lines of cut, by making the one knife o1" set of cuttersto traverse through or across the cutting-edge of the other cutter; alsoin which, to facilitate this act-ion of the cutters, a sectionalcutting-block was used, the-ends ofwhich were made to yield or slide,but so as, while admitting ofthe passage .of the cross-cut knivesthrough the block and longitudinal cutter, a close or unbrokencutting-edge was secured to the latter; likewise in which machine therewere arranged on'an intermittently-rotating feed-roller, creasing andembossing-strips, operating in concert with cutters that afterwardsshaped and detached the article. All of these features arcor may be usedin-this myimprovement, thenature of which consists in a novelcombination,

with-such longitudinal andcross-cutting devices, of additionallongitudinal cutters, for securing both a curved and straightlongitudinal out, for the formationof collars or other articles of acurvilinear contour.

Referring to the accompanying drawing, which represents the machine'asconstructed for the manufacture of collars, of paper or paper cloth,ofavhat is known as the Shakespeare style, or by other terms as appliedto ladies collars, but in both of which the one or both longitudinaledges, instead of being straight, are of curvilinear form, it will beunnecessary here to describe minutely all or the general details, whichare or may be the same as those described in my former patent, hereinpreviously referred-to. Thus, A A are the feed-rollers to thc sheet, theoneof whichmay orlnay not have arranged on its periphery creasing orembossing-strips; or the creasing and embossing and formation ofthe'button-holes may he afterwardseiected on the cutting-blocks by theaction of the platen; or, say, the upper one, A, of thesefeeding-rollers may be` provided with metallic embossing-plates, havingsome fanciful design upon them,'in which case it is'preferable to makethe periphery of the lower roller A of a soft or-exible'character, thatmay be done by covering or otherwise. An intermittent rotary motion maybe given to the roller A, to eli'ect'the feed, by a. r'od,'a, connectedby an arnnl), to'a continuously-revolving shaft, B; said rod beinggeared at its lower end to alever, c, that serves to actuate a ratchetor other` device on the end of the roller A, so as to give to the latterthe requisite intermittent rotary Vmotion. The driving-shaft B iscarriedbythe upper portion of the frame C of the machine. rlhe sheet ofpaper orpaper cloth fed by therollers A A', each intermittent action the widthof a collar, is passed on to or over the cutting-block Dfwhere it issubjected to the action of the platen, and cut or shaped, and it may bccreased or embossed and the button-holes formed, vmuch in the samemanner as in my former machine before referred to.` Thus, E is thevertically-reciprocating platen, that maybe operated by a slide, F, rodG, and eccentric, H, on the shaft B. D, the cutting-block, for operationin connection with the longitudinal cutter I, carried by the platen, andJ they sliding or opening end-sections to the cutter-block, for thepassage through or between them of the cross-cuttersK, andso as tointersect the longitudinal cut of the knife I'and .block D. Here,however, instead of the sections J being opened by the cross-cutters Kin their descent, they are drawn apart 'from the main block D, by theaction of bevel-nosed studs al, connected with the platen, ac ting, inthe descent of the latter, on reversely-bevelled studs c, attached tothe sliding sections, which springs 'f serve to close on the ascent ofthe platen.: T his mode of ppeningfthe sliding sectionsv J'f prevents]dn'lling of thcl crossf cutters K.
